Appian describes the last days of the Roman siege of Carthage (146 BC):

When daylight came Hasdrubal, enraged at the attack upon Megara, took the Roman prisoners whom he held, brought them upon the walls, in full sight of their comrades, and tore out their eyes, tongues, and tendons with iron hooks; of some he lacerated the soles of the feet, he cut off the fingers of others, and some he flayed alive. All who survived these tortures he hurled from the top of the walls. He thus gave the Carthaginians to understand that there was no possibility of peace with the Romans, and sought to fire them with the conviction that their only safety was in fighting. But the result was contrary to his intention, for the Carthaginians, conscience-stricken by these nefarious deeds, became timid instead of courageous, and hated Hasdrubal for depriving them of all hope of pardon.
